Note: The kind of animation were going to produce is called computed animation, in which the
position of an object is recalculated by a computer program and the object is then redisplayed. This is
in contrast to cel (or frame-by-frame) animation, which uses predrawn individual static pictures.
Animated gifs are examples of cel animation and can be produced in many graphics programs. The
Flash authoring tool is excellent for producing and integrating computed animation and cel animation.
Flash also has facilities, such as tweening, to help produce the individual static pictures.
Youll have to imagine the animation represented by these static pictures. In Figure 3-1, notice the form
with fields for setting the horizontal and vertical velocity.

In Figure 3-2, the ball has been replaced by an image and the walls are filled in using a gradient.
